Dometic 385314349 Toilet Water Valve Assembly, Screws Included | Easy, Installation

This worked just right on my Dometic 510 toilet. The improved brass shaft should hold up quite well. I lubricated the o-rings on the shaft with silicon grease so they would slide in without getting nicked and to help them seal better. After I installed the ball I sprayed it and the entire waste tube down with silicon spray. I also applied the silicon spray to the ball seals on all sides to keep everything lubed well. She now holds water like a champ and doesn't leak. This was part of a complete rebuild where I replaced the vacuum breaker, the water valve assy and upgraded the sprayer with a much improved hose. I also had to repair a water damaged floor which I built up under the toilet to elevate it 16 1/2" high, a big improvement.Parts used:- Dometic 385230335 Vacuum Breaker Hand Spray Kit - this was the wrong one for the 510, the pipe going into the back of the toilet was too short. I used about 1.5" 5/8 inside diameter clear nylon tubing to slip over the plastic pipe and added about 2" of 1/2" CPVC and a couple of hose clamps to secure it all together and now it works like it was meant to. By the way the plastic pipe going to the toilet is not a standard size of CPVC, PEX, or PVC so none of those couplings would have worked. Item that I should have used is the Dometic 385230325 Vacuum Breaker Hand Spray Kit with Extension, but my extension works so I'm leaving it at that for now.- Dometic SE341549 385310063 Floor Flange Seal which I lubricated all over with dish soap like the instructions advised.- Dometic 385316140 Rubber Seal Kit for Toilet - Black/Gray- SmarterFresh Rounded Bidet Sprayer Head Only, Stainless Steel Brushed Nickel Diaper Sprayer Bidet Head with a length of Stainless Steel Handheld Shower Hose that I had left over from other projects This spray head doesn't leak and looks a lot better, it will not fit in the spray head retainer from Dometic- Sanilo Elongated Toilet Seat, Wide Choice of Slow Close Toilet Seats, Molded Wood, Strong Hinges (Sea Breeze)- Luxe Bidet Neo 320 - Self Cleaning Dual Nozzle - Hot and Cold Water Non-Electric Mechanical Bidet Toilet Attachment (blue and white). I added a hot water line into my water closet for the bidet. While not expensive this bidet is great and saves putting a lot of toilet paper into the tank.So now my 22 year old toilet works like new again, the toilet is elevated, which makes it more comfortable for me, I now have a bidet, and it all looks great.

I bought this for our 2012 Newmar Bay Star which we have owned since 2018. Sure enough, on our first trip of the year, we start getting water around the base of the toilet. At first, I thought it was going to be time for a new toilet, but some online research taught me that this valve assembly is quite often the culprit. I also read that this valve can be difficult to winterize, and if not fully winterize winterized, it will freeze and then leak. Apparently, you want to flush the toilet several times while you are in the process of pumping antifreeze through your water system.Installation is anywhere from very easy to difficult depending on working area around the toilet and water lines. There are two water lines attached to the valve assembly. The lower one has a screw on adapter, and the pex line was secured with a stainless steel screwdriver clamp. The upper water tube is pushed onto the valve's fitting and secured with another clamp. But, you have to look at what clamps are used on your set-up and be prepared. I thought I was going to have to use pex stainless steel clamps and bought a kit with the needed tool and clamps. But...when the floor pedal was removed, I could then see that screwdriver clamps were used.Consider attaching the water lines to the valve assembly first if your working space is limited. The valve assembly is attached with two screws. Alternate between the two as you tighten them and don't over tighten them.The valve assembly is somewhat pricey for what it is, but I would rather pay for a Dometic valve rather than taking a chance with a different brand, even though the joke may be on me because they may come off the same assembly line in China! And, my three star rating for "easy to install" is due to small work area around our toilet. I had to use stubby screwdrivers and install the lower water line to the valve assembly before screwing it in place.

This flush valve by dometic was a perfect fit on the motorhome

Easy to install and 5 years later and it’s still working.

Perfect.Thank you.

This is an exact fit for my Sealand (Dometic) 510 toilet. It was about a 10 minute install. The screws that came with it have a different thread pitch than my existing screws, so I didn't use them. The valve works great.

The water valve was for tv toilet and was simple to change out and could flush again

Works well good price
